LIQUIDI-COOLER.

SPECIFICATION forming part of Letters Patent No. 736,221, dated August11, 1903..

l Application filed February 6, 1903. Serial Noy 142,196. (No model.)

T all whom t may concern,.-

Be it known that I, MILES A. CONNOR, a citizen of theUnitedStates,residing at Lockport, in the county of Niagara and State ofNew York, have invented new and useful Improvements in Liquid-Coolers,of which the following is a specification.

This invention relates to the class of coolers designed more especiallyfor cooling beer and comprising a tank containing ice, a liquidchamberembedded in the ice, an inlet or supply pipe leading from the barrel orother receptacle to the liquid-chamber, and a discharge-pipe leadingfrom the chamber to the dispensing-faucet.

One object of my invention is to so arrange the inlet and dischargepipes of the coolingchamber as to withdraw the liquid from the coolestportion of the chamber andat the same time prevent the incoming uncooledliquid from commingling with the cooled liquid, thereby discharging the-liquid at a correspondingly lower temperature.

A further obj ect of the invention is to provide the apparatus with anefficient vent which, while preventing leakage of liquid from thecooling-chamber, insures the com- Vplete` filling of the chamber at alltimes, thus always utilizing the full cooling capacity of the apparatus.j l i In the accompanying drawings, Figure 1 is a sectional elevation ofthe apparatus. Fig. 2 is a horizontal section of the cooling-chamber inline 2 2, Fig. 1.

Similar letters ofreference indicate corresponding parts inboth figures.

` A indicates the outer box or tank of the cooler, having a door orcover A at its top for introducing the ice or other refrigerating agent.

B is the cooling-chamber arranged in the tank and consisting,preferably, of an upright glass cylinder and metallic heads B B2,applied to its ends and clamped against the same bylongitudinal tie-rodsO. To the upperend of these rods are applied thumb-nuts c, which uponbeing removed. permit the separation of the upper head and the cylinderfor cleaning these parts when necessary. Gaskets of rubber or othersuitable material are interposed between the glass cylinder and itsheads to form tight joints. Y

D is the liquid-supply pipe leading from a barrel or other source ofsupply, (not shown in the drawings,) and D the inlet-pipe of thecooling-chamber, which is connected with the supply-pipe by a union D2or other suitable joint. This inlet-pipe extends upwardly into thecooling-chamber B through a tube or nipple e, depending from the lowerhead of the chamber. This nipple passes through the bottom of theice-tank A and is externally screw-threaded to receive a clamping-nut f,which bears against the under side of the tank for holding thecooling-chamber iirmly in place. A valve G is preferably arranged in thesupply-pipe D for shutting off the iilow of liquid to thecooling-chamber while cleaning or repairing the same.

As shown in Fig. 1, the inlet-pipe extends nearly to the top of thecooling-chamber, so as to deliver the uncooled liquid into the upperportion thereof. j

H H indicate the discharge-pipe of the apparatus, which passes upwardlythrough the top of the cooling-chamber and extends through the wall ofthe tank A, Where it terminates in a suitable faucet or valve I. Thispipe is preferably composed of two sections, which are connected at thetop of the coolingchamber by a suitable union-joint J. The nut j of thisjoint engages with a screwthreaded nipple k, which extends upwardly fromthe top head of the cooling-chamber and through which the lower sectionH of the discharge-pipe passes, the upper end of this section beingiianged outwardly and clamped between the end of said nipple and the op-`posingtnember of the union-joint. This joint permits thecooling-chamber to be detached from the upper horizontal section H ofthe discharge-pipe for cleaning it. The nuts of the unions D2 and J maybe provided with knobs or handles d and j', respectively, forconveniently turning the same.

The lower section of the discharge-pipe eX- tends nearly to the bottomof the cooling-l chamber, as shown, so as to receive the liquid from thelowest or coolest portion of the chamber. The inlet and discharge pipesof this ICQ chamber preferably pass centrally through the heads B Bzofthe chamber and are oifset or bent outwardly, as shown at b 11',forclearing each otherA This offset brings the pipes close to the sidesof the chamber, and each continues in a course parallel to the side ofthe chamber to a point near the head opposite that by which it entered.

By terminating the inlet-pipe near the top of the cooling-chamber andthe dischargepipe near the bottom of the same the incoming uncooledliquid is prevented from commingling at once with the coolest liquid inthe lower portion of the tank and reducing the temperature of the same.Thev agitation produced by the incoming liquid takes place in the top ofthe chamber remote from the region Where the liquid is coldest, theentering liquid descending quietly as it becomes cooled and finallymingling with the liquid in the bottom of the cooling-chamber, thusalways drawing the liquid from the coldest level.

To permit the air to escape from the cooling-chamber and avoid theformation of an air-cushion above the liquid, the dischargepipe H isprovided at or near the upper head B with a vent-opening l. The air inthe chamber enters the discharge-pipe through this opening and escapesthrough the faucet in drawing liquid. By thus combining the vent withthe liquid-discharge pipe the liquid while being permitted to completelyfill the cooling-chamber cannot leak therefrom, as it could if avent-aperture were formed in the top oi' the chamber, and the chamber isat the same time vented automatically in the act of opening thedispensing-faucet, thus always obtaining the maximum cooling capacity ofthe apparatus.

I claim as my invention In combination in a beer-cooler, acoolingchamber vertically disposed, an inletpipe entering centrallythrough the lower head, an outlet-pipe extending centrally through theupper head, each of said pipes being bent laterally adjacent to the headand within the chamber and said bends extending in opposite directionswith respect to each other and each pipe having a straight terminalportion, that of the inlet-pipe opening within the chamber at or nearits upper end and that of the outlet-pipe being located within thechamber at or near the lower head, said straight portions being locatedat the greatest distance from each other whereby the cool liquid will besubject to the minimum extent to the inluence of the incoming warmliquid.
